Thunnus tonggol is a species of tuna of tropical Indo-West Pacific waters.
It is commonly known as the longtail tunaor northern bluefin tuna. The usage of the latter name, mainly in Australia to distinguish it from the southern bluefin tuna, leads to easy confusion with Thunnus thynnus of the Atlantic and Thunnus orientalis of the North Pacific. Compared to these "true" bluefins, Thunnus tonggol is more slender and has shorter pectoral fins.
Thunnus tonggol reaches 145 centimetres (57 in) in length and 35.9 kilograms (79 lb) in weight. Compared to similar-sized tunas, its growth is slower and it lives longer, which may make it vulnerable to overfishing.
A tuna is a saltwater fish that belongs to the tribe Thunnini, a subgrouping of the Scombridae (mackerel) family. The Thunnini comprise 15 species across five genera, the sizes of which vary greatly, ranging from the bullet tuna up to the Atlantic bluefin tuna. The bluefin averages 2 m (6.6 ft), and is believed to live up to 50 years.
Mackerel is a common name applied to a number of different species of pelagic fish, mostly from the family Scombridae. They are found in both temperate and tropical seas, mostly living along the coast or offshore in the oceanic environment.
The mackerel, tuna, and bonito family, Scombridae, includes many of the most important and familiar food fishes. The family consists of 51 species in 15 genera and two subfamilies. All species are in the subfamily Scombrinae, except the butterfly kingfish, which is the sole member of subfamily Gasterochismatinae.
The albacore, known also as the longfin tuna, is a species of tuna of the order Perciformes. It is found in temperate and tropical waters across the globe in the epipelagic and mesopelagic zones. There are six distinct stocks known globally in the Atlantic, Pacific, and Indian oceans, as well as the Mediterranean Sea. The albacore has an elongate, fusiform body with a conical snout, large eyes, and remarkably long pectoral fins. Its body is a deep blue dorsally and shades of silvery white ventrally. Individuals can reach up to 1.4 m (4.6 ft) in length.
The Atlantic bluefin tuna is a species of tuna in the family Scombridae. It is variously known as the northern bluefin tuna, giant bluefin tuna [for individuals exceeding 150 kg (330 lb)], and formerly as the tunny.
The yellowfin tuna is a species of tuna found in pelagic waters of tropical and subtropical oceans worldwide.
The term billfish refers to a group of predatory fish characterised by prominent bills, or rostra, and by their large size; some are longer than 4 m (13 ft). Billfish include sailfish and marlin, which make up the family Istiophoridae, and swordfish, sole member of the family Xiphiidae. They are apex predators which feed on a wide variety of smaller fish, crustaceans, and cephalopods. These two families are sometimes classified as belonging to the order Istiophoriformes, a group with origins in the Late Cretaceous around 71 million years ago with the two families diverging from one and another in the Late Miocene around 15 million years ago. However, they are also classified as being closely related to the mackerels and tuna within the suborder Scombroidei of the order Perciformes. However, the 5th edition of the Fishes of the World does recognise the Istiophoriformes as a valid order, albeit including the Sphyraenidae, the barracudas.
The black marlin is a species of marlin found in tropical and subtropical areas of the Indian and Pacific Oceans. With a maximum published length of 4.65 m (15.3 ft) and weight of 750 kg (1,650 lb), it is one of the largest marlins and also one of the largest bony fish. It is one of the fastest fish species as well, having been recorded unwinding fishing line at 82 mph (120 ft/s). Black marlin are fished commercially and are also a highly prized game fish.
The Bigeye tuna is a species of true tuna of the genus Thunnus, belonging to the wider mackerel family Scombridae.
Fistularia tabacaria, the cornetfish, bluespotted cornetfish, tobacco trumpetfish or unarmed trumpetfish, is a species of cornetfish found along the Atlantic coasts of the Americas and in the central Atlantic off west Africa and the Macaronesian Islands. This species is of minor importance in commercial fisheries.
The southern bluefin tuna is a tuna of the family Scombridae found in open southern Hemisphere waters of all the world's oceans mainly between 30°S and 50°S, to nearly 60°S. At up to 2.5 metres (8.2 ft) and weighing up to 260 kilograms (570 lb), it is among the larger bony fishes.
The blackfin tuna is the smallest tuna species in the genus Thunnus, generally growing to a maximum of 100 cm (39 in) in length and weighing 21 kg.
Thunnus is a genus of ocean-dwelling, ray-finned bony fish from the mackerel family, Scombridae. More specifically, Thunnus is one of five genera which make up the tribe Thunnini – a tribe that is collectively known as the tunas. Also called the true tunas or real tunas, Thunnus consists of eight species of tuna, divided into two subgenera. The word Thunnus is the Middle Latin form of the Ancient Greek: θύννος, romanized: (thýnnos), lit. 'tunny-fish' – which is in turn derived from θύνω (thynō), "to rush; to dart". The first written use of the word was by Homer.
The Pacific bluefin tuna is a predatory species of tuna found widely in the northern Pacific Ocean, but it is migratory and also recorded as a visitor to the south Pacific.
Barbara Block is an American marine biologist and Charles & Elizabeth Prothro Professor of Biology in Marine Sciences at the Stanford University Hopkins Marine Station and a co-director of Stanford University's Tuna Research and Conservation Center, with the Monterey Bay Aquarium. She has published numerous bodies of work throughout her career in marine biology and chemistry, mainly focusing on the biology and chemistry of metabolism in different tuna and shark species. Additionally, she has helped develop two new types of electronic tags for large pelagic predators in order to track the migrations of large oceanic predator species.

Thunnus (Neothunnus) is a subgenus of ray-finned bony fishes in the Thunnini, or tuna, tribe. More specifically, Neothunnus is a subgenus of the genus Thunnus, also known as the "true tunas". Neothunnus is sometimes referred to as the yellowfin group, and comprises three species:
